<span>We need to calculate the equivalent amount in units of moles of ammonium ions from the mass units. For this we need the molar mass of the substances involved. We calculate as follows:
31.3 g </span>(NH4)2CO3 ( 1 mol (NH4)2CO3 / 96.09 g (NH4)2CO3) ( 2 mol NH4 / 1 mol (NH4)2CO3 ) = 0.65 mol <span>ammonium ions</span>
#7 is D because you move the decimal 4 places
D IS THE ANSWER TO YOUR QUESTION
The answer will be 6CO2 + 6H2O ——-> 1 C6H12O6 + 6O2
